The Green Widow Tetra is a selectively bred color morph of the Black Widow Tetra (Gymnocorymbus ternetzi), a freshwater fish species popular in the aquarium hobby. The “green” coloration is achieved through genetic modification or selective breeding, and they are often grouped with other color variants like blue, purple, or pink widow tetras.
Here's a full breakdown of the Green Widow Tetra:

Fins: Dorsal and anal fins are typically more pronounced and may be slightly transparent
-
Size: 5–6 cm (2–2.5 inches) at maturity
🧬 Genetically Modified vs. Selectively Bred
-
GloFish Green Widow Tetra: Modified with jellyfish (GFP) genes to produce fluorescent green color that glows under black/blue light
-
Selective Breeding: Some greenish variants may exist without GMOs, though less vivid and not bioluminescent
🐟 Behavior & Temperament
